Highlights

Metallic CBN Sharpening Stones from Poltava Diamond Tools are designed for guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible systems). CBN (Cubic Boron Nitride) is the second-hardest material after diamond, providing high endurance and low wearing rate with copper-tin alloy bonding.

Description

The Premium series of Metallic CBN Stones features a 3 mm thick CBN-bearing metal plate mounted on a high-quality aluminum blank. The CBN grain is made in the USA.

CBN offers exceptional hardness, strength, abrasion resistance, thermal, and chemical resistance, surpassing synthetic diamonds and conventional abrasives like silicon carbide and aluminum oxide.

Due to its high thermal stability and chemical resistance, CBN is suitable for sharpening in conditions where synthetic diamonds are not typically used. CBN stones can be used without lubricants, making them the cleanest option among available sharpening stones.

Metallic CBN stones may have tone imperfections. They may become darker over time due to natural metal oxidizing, but it does not affect the sharpening process. These stones do not require any special preparations.

Unlock your machine's potential
***Twist the WDT tool to remove dont try to just pull, or use your finger nails A slight twist will break the magnetic bond and the tool just comes out of the handle*** i got this to get away chemicals, hot acidic coffee possibly leaching plastic and aluminum that the stock portifilter is made from. This seems like a nice stainless by the looks and heft of it. Aluminium is bad for the brain and plastic is just bad. Function... Im not using a 200$ or more grinder or anything... Just fresh beans and a 30$ wancle amazon burr grinder and this is pulling beautiful bottomless shots that really helped me dial in better and see my channeling issues that intern lets me adjust and get better. The stock tapered basket prevents consistant tamps and keeps you from using off the shelf filter papers at the bottom of the basket. i have to use a gram or 2 more for my dose but that just means stronger drinks. I can tell visually im getting more extraction now that im dialed in by the color after adding milk.

It doesn’t even fit
It doesn’t fit our Breville Barista Pro because the portafilter head is too tall. Such a disappointment. Update: Absolutely horrible customer support as well. Their only attempt to rectify the situation was by double checking their own portafilter they have and confirming it works. It’s equivalent of “we investigated ourselves and found nothing wrong.” No replacements, no willingness to accept constructive criticism in order to change the dimensions slightly by decreasing the height of the portafilter head by even a millimeter to make it work, nothing. Just a slap in the face telling me to return it and be gone. Avoid this product.

More work than it’s worth
It was great quality and the weight was nice, but it was odd having the open bottom and no spout to dribble into a cup when making an espresso. It was difficult to get the wire tool out of the end of the handle, making it difficult to use. I was not that impressed and it’s quite expensive.

Quality and Function
Looks like a silly little thing, I am not a coffee enthusiast. But it does exactly what it is supposed to do and with high quality. The device (a stretch to call it that) is made of sturdy materials including the needles. They give you two different thicknesses of needles, one for expressi (0.3) and one set for coffee grinds (0.4). Each comes wth some spares. The stand is well designed and keeps grinds from spreading all over. It is very elegant design. I use this with a dosing funnel on my portafilter. Not the cheapest one could buy but well worth the money.
